El solar: Sitio de conservación de germoplasma y biodiversidad, en tres localidades del municipio de Cárdenas, Tabasco.
Provedor de dados: 32
Autores: Torres Rosas, Nubia Nitzel.
Se estudiaron 6 solares familiares, en tres localidades del municipio de Cárdenas, Tabasco; que representan tres zonas fisiográficas diferentes: zona de Llanura Aluvial, zona de Vega de Ríos y zona  Costera, siendo respectivamente, el Poblado C-28 (Coronel Gregorio Méndez Magaña), el Ejido Miguel Hidalgo 2da. Sección B (La Natividad) y el Ejido Sinaloa 1ra. Sección. La investigación se realizó desde dos vertientes, el botánico y el social, la primera comprendió el análisis de la diversidad florística y de usos en los solares, obteniéndose como resultado la identificación de un total de  130 especies con 16 propósitos de uso. Los índices de diversidad fueron relativamente altos (H’= 2.20 - 3.43, DMg = 4.38 - 10.15), al igual que los valores de equitatividad...

Etnobotánica del ejido Sinaloa 1a. sección, Cárdenas Tabasco, México.
Provedor de dados: 32
Autores: Gómez García, Erika.
Los huertos familiares en los trópicos tienen una gran importancia social, económica y ecológica. Con la finalidad de determinar la flora útil y sus usos, se realizó el presente trabajo de investigación etnobotánica en el Ejido Sinaloa 1a sección, municipio de Cárdenas, Tabasco. Se determinó el tamaño de muestra de 73 hogares, en los que se preguntó acerca de las plantas sus usos y las partes usadas. El trabajo de campo se realizó de febrero de 2009 a junio de 2010. Una vez realizadas las entrevistas, se utilizó el método de bola de nieve para calcular el índice de valor de uso, se pidió a cada entrevistado que mencionara a una persona que él supiera que utiliza las plantas con relativa frecuencia. Se seleccionaron 10 informantes clave  los cuales fueron...

Separating Adaptive Maintenance (Resilience) and Transformative Capacity of Social-Ecological Systems
Provedor de dados: 7
Autores: Wilson, Samuel; Melbourne Sustainable Society Institute, The University of Melbourne, Australia; Present address: School of Psychology and Psychiatry, Monash University, Australia;; Pearson, Leonie J; Melbourne Sustainable Society Institute, The University of Melbourne, Australia; Land and Environment, The University of Melbourne, Australia; lpearson@unimelb.edu.au; Kashima, Yoshihisa; Melbourne Sustainable Society Institute, The University of Melbourne, Australia; Psychological Sciences, The University of Melbourne, Australia;; Lusher, Dean; Swinburne Institute of Social Research, Swinburne University of Technology, 3122 Australia;; Pearson, Craig; Melbourne Sustainable Society Institute, The University of Melbourne, Australia;.
Many rural communities are vulnerable social-ecological systems (SES) that must do more than become resilient to future environmental and social shocks: they must transform to achieve sustainability. We aimed first to conceptually explore the proposition that SES characteristics (identity, feedbacks, structure, and functions) necessary for transformation may be distinct from those necessary for adaptive maintenance or resilience, and second, to propose metrics that may be used to assess these two types of system changes. We did this by interrogating literature and by investigating two rural towns in Australia using a combination of  quantitative methods and focus groups to interrogate community social networks, capitals (human, natural, built, and social)...

The crustacean selenoproteome similarity to other arthropods homologs: A mini review
Provedor de dados: 69
Autores: García-Triana,Antonio; Yepiz-Plascencia,Gloria.
Selenoproteins (Sels) are involved in oxidative stress regulation. Glutathione peroxidase (GPx) and thioredoxin reductase are among the most studied Sels in crustaceans. Since their expressions and activities are affected by pathogens, environmental and metabolic factors, their functions might be key factors to orchestrate the redox cellular balance. The most studied invertebrate selenoproteome is from Drosophila. In this fly, SelD and SelB are involved in selenoproteins synthesis, whereas SelBthD, SelH and SelK are associated with embryogenesis and animal viability. None of the Sels found in Drosophila have been identified in marine crustaceans yet, and their discovery and function identification is an interesting research challenge. SelM has been...

Speaking Stata: On getting functions to do the work
Provedor de dados: 31
Autores: Cox,   Nicholas J.
Functions in Stata take two main forms, built-in functions that are part of the executable and egen functions written in Stata’s own language. These are surveyed, giving a variety of tips and tricks, and noting the large number of user-written egen functions available for download from the Internet. Two substantial examples, the calculation of percentile ranks and plotting positions, and the calculation of measures summarizing properties of the other members of a group, provide detailed illustrations of egen in action.

Speaking Stata: Rowwise
Provedor de dados: 31
Autores: Cox,   Nicholas J.
Stata’s main data model treats observations in rows and variables in columns quite differently, but rowwise problems also arise that require working against the grain. This column shows how to exploit existing functions and egen functions when they exist and apply to such problems. It offers advice on how to build your own loops, egen functions, or programs when needed. Mata provides especially convenient tools for constructing many such functions and programs, centered on putting selected data into matrices and then processing each observation as a separate vector. Two programs, rowsort and rowranks, are formally published with this column.

An alternative for antibiotic se in poultry: probiotics
Provedor de dados: 89
Autores: Edens,FW.
Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Evidence has been accumulated to show that there is a link between risk of zoonotic disease and growth promoting antibiotic usage in livestock and poultry. Therefore, alternatives to the use of growth promoting antibiotics must be found to promote growth or production at or near the genetic potential of the modern day broiler, turkey, and egg producer. The use of probiotics has many potential benefits and include modified host metabolism, immuno-stimulation, anti-inflammatory reactions, exclusion and killing of pathogens in...
